Content-defined chunking added to Bazel

BuildBuddy가 Bazel 원격 캐시에 Content-Defined Chunking(CDC)을 도입해 대형 빌드 출력물의 중복 데이터를 효율적으로 재사용한다. CDC는 파일 내용을 기준으로 청크를 나누어 변경된 부분만 전송하고 저장하여 네트워크 사용량과 디스크 캐시 크기를 약 40% 줄였다. 이 기술은 특히 GoLink 같은 트랜지티브 액션에서 작은 소스 변경이 대용량 출력물 전체를 다시 업로드하는 문제를 해결하며, 수백 테라바이트의 중복 데이터 전송을 방지해 빌드 효율성을 크게 향상시킨다. Bazel 8.7 이상에서 실험적 기능으로 활성화 가능하다.

I'm looking for a #Bazel #Monorepo engineer to work in my team in a full-time, hybrid role with 3 days per week in the office in either #Bristol or #London, UK.

Things are moving fast at Fractile, so I'm looking for someone who has the experience to hit the ground running, and get up to speed on our custom rules, RBE, Remote caching, etc., quickly and then help shape the future of the monorepo and how we use Bazel across the company.

Exploring an #AI workflow for automatically fixing flaky tests, and having reasonable success with it.

#Bazel is actually a particularly nice fit with features like `--runs_per_test`. I expect any Bazel #web workspace could probably use this prompt mostly as-is.

Quick #story time: I was on a team which accidentally shipped sourcemaps to production!

The production server would serve sourcemaps for local dev, and we built sourcemaps in prod to deobfuscate errors but they weren't provided to the server in the prod environment.

You might see the hazard there. An innocuous change to our #Bazel build structure accidentally pulled in sourcemaps into the server, which it then helpfully served.

This was an app in the #Google monorepo too, so we were revealing all our source code as well as all our dependencies!

Het is misschien een beetje over de top, maar in #Bazel maken ze de #belastingen dus wel een beetje leuker (niet perse makkelijker). Vooral het "bedankt voor je waardevolle bijdrage aan ons Kanton" vind ik wel een prettig staaltje #communicatie.

Hoe is dat tegenwoordig in nederland? (lang geen blauwe envelop meer gehad)

Read on #Guix science channel about #Bazel:

« The offending upstream commit is here: github.com/tensorflow/tensorflow@e85860e838

There is no way to build Tensorflow without a bundled Python toolchain. The only way I see is to trick it into "downloading" our provided Python toolchain from a file:// URL.

I find this battle against upstream's approach towards reproducibility exhausting. »

🤔 Could you stop to say: “yeah Guix is great but I don’t use because it doesn’t provide what I need”…

…and instead explicitly say: “my research outcome is more important than doing it correctly”.
